It's been a long day for you, as your boyfriends have been gone almost the entire day due to mandatory meetings. Luckily, you didn't have to attend, but it meant you'd been bored for a while. You’ve tried everything from reading a book to watching TV; your apartment is spotless, and now you're scrolling on your phone on the bed, feeling restless.

Your phone is thrown to the side with a huff, and you look around the bedroom when your eye suddenly falls on a small, rectangular box in the closet, and you instantly get excited. Within the blink of an eye, you're standing in front of the closet, the black box feeling heavy in your hands, arousal already pooling in your panties at the thought of what you're about to do.

The walk back to the bed is quick, and you're soon undressed, leaving you completely bare as you sit back down on the bed, box in hand. Your heart is racing as you think about the moment Bucky handed you the box, a beautiful red bow tied around it.

"I got you something... personal, Printsessa," Bucky tells you; all your birthday guests have just left. You're alone with one of your boyfriends in the kitchen, cleaning up the cups and other trash when you turn to meet his gaze. A sparkle of mischief is visible in his bright blue eyes, with a matching grin lighting up his features.

"But you already gave me a present! You really didn't have to do this,'' you tell him, your curiosity piqued regardless. He hands it to you, and the bow finds its way onto the counter; and when you open the box, you see an exact replica - size and girth included - of Bucky's cock. Everything from every vein to the color of it is eerily life-like, and you're already clenching your thighs in anticipation.

"Does Steve know about this?" you ask him, not wanting your other boyfriend to be left out.

"Who do you think helped me make the mold for it, Printsessa?" Bucky nearly growls, his voice deepening immensely with his own arousal coursing through his veins. He's getting hard, his cock straining against the confinement of his pants.

It didn't take long for you to be on the bed, riding the silicon replica of Bucky's cock, while he was jerking off his real one. He couldn’t stop looking at you as you took it all the way to the base, moaning Bucky's name loudly until you're both finding your release not much later. You would use that toy many more times, either with or without your boyfriends, and it is possibly the best gift Bucky could have ever gotten you.

You settle against the pillows and headrest, the toy feeling nice and heavy in your hand as you spread your legs, your phone in your hand as you're going to search for some videos to watch. It's a good thing your boyfriends aren't shy about filming during sex, so there's plenty of content for you to enjoy.

After some scrolling, you decide to go with a video where they're both fucking you at the same time and as soon as you click the start button, long, broken moans and pleas to cum fill the room. As you look at your phone, you can feel yourself slowly getting more aroused, so you bring the large toy to your pussy, dragging it through your folds as your lip is held between your teeth. A sharp feeling of pleasure courses through you as it rubs over your clit, your body jolting at the sensation.

After teasing yourself for a few minutes, you line the large tip of the dildo with your entrance before pushing in slowly, stretching you just the way you love so much. Both of their cocks always stretch you immensely, but with Bucky being just a bit bigger, it always takes a bit more time.

A moan leaves your throat as you push in more of the toy, your body slowly accepting the silicon while you keep looking at the video on your phone. The ‘you’ on screen is on all fours, Steve fucking your pussy, and Bucky has his cock in your mouth. He sets a brutal pace, and you gag around him.

It doesn't take long for the dildo to be fully inside you, and you look down to see your belly bulging slightly, just like it does whenever Bucky is deep inside you, and you can't help but grin at the sight. Seeing how deep both boys can get inside you always spurs them on; it makes them even more horny, and they never get enough of the sight.

After you've adjusted to the stretch, you slowly start thrusting the replica cock in and out, the video you were watching now forgotten as you put the phone down. Your eyes are closed as the pleasure builds slowly with every motion; every time the toy pushes in and glides out, you let out a soft moan.

Suddenly, you feel a presence in the room with you, but you don't move to cover up or stop what you're doing. Instead, you spread your legs even wider so both your boyfriends can get a better view of your glistening pussy and the toy smoothly gliding in and out. When you open your eyes, their arousal is plainly visible - both in their pants and lust-filled eyes. They look at you like they want to devour you whole.

"You're really bad at hiding how horny you are," you tell them between soft moans, and you see a deep red blush creeping over both your boyfriend's cheeks. You can see they're getting a little antsy as they stand there, wanting nothing more than to touch you, but you have an even better idea. You take your bottom lip between your teeth in anticipation, and your line of sight glides down to their crotches, seeing how hard they are as they strain against the confines of their pants.

"I want both of you on the bed, but-" you say with a pointed tone, "you can only help each other. I want to see the two of you getting each other off while you watch me make myself cum on this toy.” Bucky's eyes widen at your words, and Steve is already on his way to the bed, clothes strewn across the floor before his knees hit the bed in anticipation.

"Can I kiss you, Princess? Please, let me kiss these beautiful lips of yours,'' Steve asks as he crawls over to you, taking his place between your legs, his lips mere inches away from yours, and you can't say no to him. After a slight nod, Steve moves forward to capture your lips with his, letting your tongues dance while Bucky looks on, his metal hand slowly and loosely jerking himself.

"Look at you two; I couldn't wish for a better sight," Bucky mumbles as he takes in the view before him. Steve pulls away with a small smile dancing on his lips before sitting back on his haunches, admiring how your belly bulges with the toy.

"C'mere, Buck, look at your cock stretching her belly," he tells his boyfriend, who's nearly drooling at what he’s seen so far alone. The only way it would be even better is if it were him inside you, but he'll happily look at the toy stretching your pussy too. Once his clothes are off, he takes his place on the bed, waiting patiently for Steve.

The scene unfolding in front of you has you clenching your thighs and arousal flooding over the toy and onto the bed, more moans leaving your lips. Steve and Bucky are on their knees, chest to chest, and kissing each other passionately, their tongues dancing in a fight over dominance, each having a hand wrapped around the other's cock.

''Fuck, look at you two," you groan as your free hand glides to your clit, the toy still thrusting in and out at a steady pace as the familiar feeling of an orgasm is building in the pit of your stomach, a warmth spreading through your veins as your eyes are locked on their hands working on each other's cocks.

"Cum for us, Princess, cum for us, and after, we'll fuck you completely senseless," Steve tells you, and with a few tight circles and well-aimed thrusts, you become a moaning, writhing mess on the sheets, your arousal squirting out of you. Your legs tremble as your back arches, the toy becoming too much inside you as you pull it out, panting loudly as you keep your eyes on your boyfriends.

"C'mere, Princess," Steve says as he reaches out his hand for you, and you take it. He lets go of Bucky so you can place yourself between them, Steve in front of you, and Bucky behind you so you're in the middle of a super-soldier sandwich.

"We're so proud of you, you know that?" Bucky whispers in your ear as you let your head fall back against his shoulder, two pairs of hands wandering over your body, ensuring you're relaxed enough for everything that’s about to happen. The rest of the night, both men make you fall apart, and somewhere around the third orgasm, although you may have lost count, you fall into a deep sleep.

You're lulled into a dreamless sleep as you're pressed once again between your boyfriends, Steve behind you and Bucky in front, both of them still buried deep inside you, plugging you up so not a single drop of their cum will escape from your body. It's the best night's sleep you've had in a while, and you’ll whip out the toy more often if this is what it brings you.

Bad Dragon is suing SinSaint over copyright infringement of their dildo designs. What I want to know is, can you copyright the shape of a dog's dick? Because if you can, you shouldn't be able to.

I did knot need to hear about this one.

one more pun

TSG is gonna be one of the more reputable sources for this one

MARCH 25--A manufacturer of “fantasy-themed sex toys” has accused an upstart Brooklyn, New York firm of knocking off its distinctive designs, according to a federal lawsuit alleging that the defendant has infringed on copyrights for dildos such as “Spritz the Seadragon” and “Tyson the Water Buffalo.”

In a March 20 complaint filed in U.S. District Court in Arizona, Bad Dragon Enterprises contended that its “sculptural” products have been illegally copied by SinSaint, which is headquartered in a Coney Island warehouse and advertises that all its “Ethically Manufactured” toys are “made in Brooklyn, USA.”

Bad Dragon, which noted that it has had “significant commercial success” in the adult toy field, alleged that SinSaint has been selling the duplicative dildos through its website and other trade channels, including the recent AVN Adult Entertainment Expo in Las Vegas (where the new firm’s exhibitor booth was next to that of the all-nude Palomino strip club).

The lawsuit identifies 13 separate dildos that Bad Dragon claims have been copied (and renamed) by SinSaint, which was incorporated in New York last year. The colorful silicone toys feature scales, tentacles, suction cups, and other design elements meant to mimic the genitalia of dragons, sea creatures, and other fantastical characters.

Some of the Bad Dragon products that SinSaint is accused of swiping are “Kelvin the Ice Dragon,” “Stan the T. Rex,” and “Vergil the Drippy Dragon.” SinSaint has not been accused of pirating other Bad Dragon offerings like “Jason the Demogorgon” or “Cuttlefish of Cthulhu.”

According to the lawsuit, SinSaint’s counsel last month stated that the company had begun removing “some of the allegedly infringing listings for product redesign.” This response, Bad Dragon contended, was “unacceptable,” adding that it “continues to be harmed by Defendant’s ongoing, unlawful conduct.”

The Bad Dragon complaint seeks an order enjoining SinSaint from continuing any further alleged

copyright infringement and seeks “disgorgement of all of Defendant’s profits” related to the artificial penises. The company may also seek statutory damages of up to $150,000 for each of the dildos in question.

For more than a decade, Bad Dragon has sought trademark and copyright protection for various product lines. While often successful, the firm’s application to trademark its “Cum Tube” was abandoned after a government attorney rejected the ejaculating dildo because the “applied-for mark consists of or includes immoral or scandalous matter.” The application included a very NSFW image, which can be found on the U. S. Patent and Trademark Office website.

According to an August 2023 trademark application, SinSaint’s owner is Oleg Semenenko, 50, a resident of Brooklyn’s gated Seagate community. Semenenko lives less than a mile from SinSaint’s warehouse, which shares an address with GlobMarble, an industrial molds business for which Semenenko is listed as “manager” in a separate trademark application filed this month.

In a brief interview today, Semenenko was asked how a dildo firm grew out of his original business. “We work with rubber,” he replied. Semenenko dismissed Bad Dragon’s claim that its products were unique and original: “How can octopus hand can be your idea?” (4 pages) ____________________________________________

Hope the judge that did the recent trump case gets this one, even though I know that's basically impossible, just the thought of making him listen to hours of testimony about how these rubber fantasy dildos are protected by copyright or trademark law, or something like that is funny to me.

It's not a revenge thing wanting it, just a keep him humble thing. I know you think you're hot shit now, so here listen to these arguments for a bit.

Totally different note, I'm wondering how long until the discourse starts up, or if it has already started up, where using horse dildos is either bestiality or a gateway to bestiality because what with the way people treat cartoons of fictional people I can't imagine it's far off or not already here.

Look to japan for the tentacle ones.........

Safe Sex Resource

A lot of the time, in our writings online, we don’t always show our characters practicing safe sex (whether for narrative flow or other reasons) and will just add in our author’s notes to practice safe sex in your real life. It can be hard to find good and concise information online so I have compiled this for authors to link in their notes. I recommend everyone take a look, there might be something in here you didn't already know.

This post is largely inspired by @fakejuly who shared a lot of their knowledge and advice from their years in the sw industry, and from my own experience creating curriculums for and teaching sex & relationship education.

I have tried to make it as inclusive as possible, please let me know if you have any feedback. If you spot something I missed, please let me know. I will be updating this periodically. My inbox is also always open if you have any questions/concerns/etc.

Last update: Jan 16, 2024

wrap it up

"Condoms prevent STIs and pregnancy in the vast majority of cases, when used correctly."

Using a condom correctly and consistently can increase its efficacy from 87% to 98%. Most surveyed individuals are not using it correctly or consistently so make sure you are well-informed. We hear this all the time, but what does “used correctly” actually mean?

Familiarize yourself with the steps.

Using the right size: if it's too big, it can slide off or leak; if it's too small, it can break or come off. Condoms usually come in 5 sizes (there are options like MyONE that have 52 sizes).

Condoms can be damaged by heat. They should be kept somewhere cool (not in wallets, or sat on in back pockets, or kept in your glovebox). They also have an expiry date.

Sex can also lead to friction (heat) so condoms should be changed between activities and after about 15 minutes of any vigorous activity.

Never double up (i.e. wearing two condoms or using both an external and an internal condom).

Use lube 100% of the time (except oral sex), even if you think you don't need it, even for "lubricated" condoms (the lube mainly stops it sticking to itself). Lube should be applied to the outside, but a drop in the tip of the condom before putting it on is also a good idea.

NEVER use oil-based lube or any type of oil (e.g. lotion, vaseline, coconut oil). Water based lube is the best option. Silicone based lube can be good for sex in water (e.g. shower, pool, bath) or providing more sustaining slip, but be careful near your sex toys (more on this later).

Penetrative partners should hold the base of the condom when they pull out immediately after they ejaculate so the condom doesn't leak or come off as the penis gets flaccid.

For oral sex (vulval or anal), you should use a barrier. You can make one out of a condom. (There are also companies like Loral that make latex “underwear” that have great sensation transfer and are a very good barrier for AFAB individuals).

Sharing sex toys: Most of the sex toy safety recommends "don't share them ever" which unfortunately is impractical for some people.

If more than one person is going to use the toy (within a session or between different sessions), use a condom.

Condoms are often coated in a thin layer of silicone lube. This can react with low-quality silicone toys - there are unlubricated condoms for those - but higher-quality (platinum cured) silicone should be fine. When in doubt, spot test on the base of the toy.

As with above, always use water-based lube.

Condoms have not been proven to protect you from mold that the toy may be harboring or toxic chemicals from low-quality materials (e.g. jelly toys).

prevention is the best cure

Due to the variable efficacy of condoms, for individuals where pregnancy is a concern, it is recommended to also be using the pill, injection, IUD, etc.

Condoms (internal or external) are the only prevention for STIs. This isn't meant to be stressful - the most common STIs are treatable and often curable (more on this later).

STIs can be transmitted via fluids AND skin contact, so use condoms when you’re engaging in oral sex, hand stuff or sharing sex toys, in addition to penetrative sex.

STIs can be transmissible via any of your fluid membranes, that includes your mouth, throat, nose, and eyes.

Condoms are extremely effective against HIV, and reasonably effective against chlamydia and gonorrhea. Contracting chlamydia and gonorrhea is not the end of the world, it is curable with antibiotics but you can also be asymptomatic.

Condoms aren’t as effective at preventing herpes (symptomatically will manifest as open sores) and HPV (symptomatically will manifest as genital warts).

Everyone who is able to should get the HPV vaccine, regardless of gender or sexuality. HPV is the most common STI. Most cases resolve on their own within 2 years, but for those that don’t, it can lead to cancers of the cervix, vagina, vulva, penis, anus and throat. Almost all cervical cancers are caused by HPV. The vaccine is extremely effective.

Even if you believe you have been safe and are asymptomatic, get tested regularly. At least once a year. (Even if you are in a long term monogamous relationship).

In summary:

Try your best to be safe but in real life, shit happens, so at least stick to these three things: 1) know your safety boundaries prior to sex and don't change them for anybody, 2) talk/ask about STI status before anything begins, and 3) get tested regularly.

CONSENT IS MANDATORY.

Communication is what makes sex good. Talking about sex is sexy. :)

SiliNOT! Testing and Review

Since I run a lot of casting workshops, I've had several people in the costuming/maker community ask me my opinion on SiliNOT!, a relatively new product advertised as a budget- and eco-friendly moldmaking alternative to silicone, urethane, and other single-use materials.

I finally bought a couple of bottles to play with, so I did a test project. My experience and findings are below! (It's not a recipe blog, but if you want to skip the play-by-play and get to the TL;DR, it's under the big "In Summary" header near the bottom.)

First, if you aren't familiar with this material, SiliNOT! is a remeltable, reusable medium for making molds. Though its exact ingredients are not disclosed, it purports to nontoxic, food-safe, and compostable. It melts in a household microwave or double boiler and solidifies at room temperature (or in a refrigerator/freezer for faster results). The website is https://silinot.com/.

(I am not an affiliate, and have no connection to this company apart from having made one retail purchase from them. I just have a lot of casting experience and like trying out new products.)

The Positive Original

I’m still in the middle of a Vincent Valentine build, so I decided to test the SiliNOT! on his custom buttons. My original is a stack of various nonporous materials: an antique (probably Bakelite) coat button, an epoxy resin dome I cast using a mold I already had in my library, and some engraved Worbla’s Pearly Art for the raised detail. The button shanks won’t be added until the final casting, so the original can be mounted flat for the moldmaking process.

Sample Worbla on the left; completed button stack on the right:

The Mold

I built the mold container the same way I do for silicone pours, with the flat back of the button fixed to a styrene plate and a cylinder (actually a small paper cup with the bottom cut off) surrounding it for the walls. The lip of the cup is sealed all the way around with Monster Clay to prevent leaks.

Heating and Pouring

The SiliNOT! didn’t take long at all to heat up; I did maybe four or five 20-second bursts before it was completely fluid. The bottle does get rather warm, so hand protection isn’t a bad idea. If you have heat-resistant gloves, you can use those; I was working in my kitchen (yay for nontoxic stuff!), so I just grabbed an oven mitt with a silicone grip.

The melted SiliNOT! looks a bit like Luke Skywalker’s blue milk. It’s about the consistency of a yogurt smoothie and likes to pour in a thicker stream compared to silicone. While silicone can be stretched into a thin ribbon for delicate pours or chemically thinned with solvent for really tricky jobs, SiliNOT!'s viscosity is dependent on temperature and never seems to get quite as thin as silicone.

I’d automatically made my mold compact to conserve material (not really a concern with a reusable moldmaking material like SiliNOT!, but after using silicone for more than a decade, I’ve trained myself to be as efficient as possible), so the walls of my mold container were only about half or three quarters of an inch from my object. Because the target was so narrow, I found it difficult to accurately fill from the lowest area of the mold with the SiliNOT! The heavier pour also means more air can get trapped in or under the material.

Bubbles are one of the areas in which SiliNOT! is decidedly inferior to silicone. SiliNOT! has higher viscosity, so bubbles don’t want to rise to the surface without vigorous tapping, which can distort the mold edges or affect leveling depending on your mold container. The bubbles that do make their way to the surface are difficult to pop, even when poked with a sharp implement. Heat gun degassing doesn’t have much effect.

Since the bubble surface cools and skins over quickly, I actually had to use a tool and scoop some large bubbles completely out of the mold to allow the surface to level. Critically, the SiliNOT! is opaque, so you can’t spot bubbles clinging to the surface of your original. (This is why my first mold was a reject, and I had to repour. More on that below.)

Hardening

Once the surface had set, I carefully moved the mold into the refrigerator to cool faster. Here’s another area where some types of silicone can have an advantage: I typically use fast-curing Smooth-On products (because I always have random quantities left to use up after our casting workshops), so I rarely have to wait more than half an hour for a silicone mold to cure, regardless of its size or mass.

The SiliNOT! has to chill completely before handling, though, and discharging that amount of heat requires a fair amount of time even in a cool environment. My mold was pretty small, maybe 2 1/2” wide by 1” deep, and it still took around 40 minutes to cool completely. A larger, deeper mold could hold considerably more energy in the center, and might have to be left in the freezer for a couple of hours before use.

Demolding the Original

When the mold was completely chilled, I removed it from the refrigerator and popped it off the plastic plate I’d used for the base of the mold. The texture was very different from what I’d expected: Unlike other meltable materials (Monster Clay, et al.) that have a firm surface when cool, the SiliNOT! remains tacky, which means it promptly collects any debris that crosses its path. In my case, this meant I had to pick dog hair off the surface throughout the casting process (and I don’t want to think about what would happen if glitter had contaminated the work space).

I’d used a paper cup for my mold walls, which usually works fine with fast-curing silicone. But the SiliNOT! must have a high oil content, because the cup absorbed some of it:

Lesson learned; use only nonporous containers with this stuff.

The SiliNOT!! really wanted to cling to the edges of my original, so I had to go slow at first to avoid tearing the thin flanges of the mold off. However, it did demold nicely from the smooth surfaces, and preserved texture very well. You can see the Worbla pebbling and the engraving channels clearly in the mold (as well as some dust and dog hair, because I made the mistake of setting it down briefly):

Unfortunately, as you can see, a large bubble had stuck to my original and created a pit in the mold, so I decided to do a second mold pour. I figured I’d tear up the failed mold and put the pieces back in the bottle to remelt… and discovered I couldn’t. The mold would stretch and twist, but not tear. It also seemed to return to its original shape relatively faithfully. Here’s a video of me manhandling the mold:

As you can see, the SiliNOT! has much better stretch and recovery than many silicone products (there are silicones that stretch well -- some of the Dragon Skin products come to mind -- but they’re not typically marketed for moldmaking). This means it’s likely well suited to casting objects with moderate undercuts or oddly-shaped bits that need the mold to stretch during demolding.

You can cut the SiliNOT! easily with scissors, which is the recommended method for getting it back in the bottle when you’re ready to remelt.

Take Two

Using what I’d learned from the first pour, I did the second one inside a hard plastic ramekin. This gave me a bit more room to pour into the floor of the mold, reducing the bubble risk, and also eliminated the porous paper cup that had absorbed oil. I still had the issue with bubbles that didn’t want to pop, but there were fewer of them this time.

The ramekin made for a much cleaner mold, buuuuut there was ANOTHER BUBBLE right in the middle of the design. >.<

Take Three

Lather, rinse, repeat. Or in this case, melt, pour, chill.

This time I heated the SiliNOT! as much as I dared and did the absolute slowest, narrowest pour I could manage, giving the air extra time to escape as the mold was filled from the bottom. The risk with stringing out the pour like this is that in a thinner stream, the heat escapes faster, leading to uneven viscosity as the liquid fills the mold. I don’t think that’s a major problem for this particular piece, but it’s something to pay attention to as regards leveling and degassing, especially for larger molds that will take longer to fill.

The result of pour three:

/siiiiigh/ Well, at least the bubbles are smaller, this time. They may not show up enough to matter in the final cast. I’ll give it a try.

Casting

I had leftover workshop resin that was getting on toward the end of its shelf life, so I used Smooth-On Smooth-Cast 300 for my initial resin trial. It’s an opaque white resin with about a 10-minute cure time (the fast turnaround is why we use it for workshops).

Before pouring, I had to do a little mold cleanup where the SiliNOT! had managed to sneak under the edge of the Worbla (I think I’d loosened the corner of the star from prying it out of so many molds), but since the SiliNOT! stretches so well, it was pretty easy to invert it to get little scissors down into the bottom of the depression.

For the first cast, I didn’t use anything but the resin in order to get a baseline. Ideally I’d like to cold cast or dye the resin so I don’t have to worry about paint chipping, but since I’m doing a trial here (and need multiple buttons anyway) I figured some plain white extras wouldn’t hurt.

So, my first cast…

…smacked into a big problem, which I probably should have seen coming: The resin I’m using is a fast cure formula, which means it discharges a fair amount of heat as it's going through that rapid chemical reaction -- enough heat to melt the SiliNOT!, as it turned out. When I tried to demold it (after giving it a few extra minutes beyond label time to be sure it was done), the surface of the mold had melted to the resin and even embedded itself in a few places. It’s difficult to see the resin detail in the photos (my camera went into white balance panic mode with all the shades of white and blue), but you can see how pitted the formerly-smooth mold surface is.

In fairness to the SiliNOT!, the bottle does say that you should put the mold in the freezer for half an hour before casting high-temperature materials. But I assumed high-temperature material was something like candle wax or melted chocolate, rather than ordinary resin. (And the mold had just come out of the refrigerator.)

So, on to pour FOUR of the SiliNOT! mold…

Take Four

NGL, this is getting a little old. >.<

Fourth mold definitely needed some cleanup around the edges, and there are still a couple of tiny bubbles I can’t seem to get rid of, but it’s good enough for a test. (I’m starting to despair of using these for actual production, given how many times I’ve had to redo the molds because of bubbles...)

Deep in the recesses of my basement, I found some transparent epoxy resin with a 24-hour cure time -- much slower and lower-temperature than the Smooth-Cast. Since it cures clear, I went ahead and mixed in some metallic powder pigment on the off chance that I get a usable button out of this one. I had excess resin after mixing, so I poured that into my first mold, which has a bubble in the design but is otherwise fine. Two test pieces are better than one, right?

Results

Here are the results of the slow-curing resin out of mold #4:

Finally, a (mostly) clean cast!

As you can see, the detail reproduction is excellent -- certainly on par with the pulls from the silicone mold I ended up making while waiting on this set to cure (purely for time reasons; I couldn’t afford five days to cast the buttons using slow-curing resin, and with a silicone mold and fast-curing resin I could get them all done within a couple of hours).

However, you can also see a few spots where bits of the SiliNOT! embedded themselves in the final cast. Part of that may be due to design flaw in the original; I didn’t want to glue anything permanently to the antique button, and that resulted in a tiny gap between the button and the resin hemisphere. Silicone has enough strength to resist tearing out in that kind of area, but apparently the SiliNOT! doesn’t. The bits of mold around the outer edge seem to have stuck just to be difficult, as there was no structural reason for those to have become embedded in the resin. This means the mold could be damaged by successive casts, reducing its usable life and accuracy.

Still, the mold definitely produced decent results for a first cast, and a different shape might not have had as much of a problem with tearing off mold parts. The slow-curing resin is a bit of a limitation, but not a unique one (I use this same epoxy resin for any glass-clear casts I do, and only use the Smooth-Cast 300 for opaque items or things I need very quickly). I don’t personally use UV resin, but I’d be curious to learn how it performs with the SiliNOT!

IN SUMMARY:

Here’s the TL;DR on SiliNOT!

Pros

Cost effectiveness. This is the most obvious advantage of SiliNOT! over silicone; it’s (theoretically) infinitely reusable, and even with natural attrition/inevitable contamination from use, you can likely get over a hundred pours out of a bottle. That's a lot cheaper per use than silicone.

Non-toxicity. SiliNOT! is touted as food contact-safe, so you don’t have to panic if you get it on your skin or kitchen counters. While platinum-cure silicone is also relatively harmless (some varieties are labeled for food or life casting), other common moldmaking materials such as tin-cure silicone or urethane are not. (NOTE: Since the company is very hush-hush about what actually makes up the SiliNOT! secret formula, I do not know if it might release any vapors or fumes that would be irritating or harmful to pet birds. In general, I advise not doing any kind of casting around birds.)

Eco-friendliness. This is the biggest draw for me personally: Given the number of casting workshops I run and all the things I sell commercially, I have constant guilt about the amount of waste I generate for creative projects. In most areas of life I’m an aggressive reduce/reuse/recycler and try to use organic materials instead of synthetics whenever possible, so a mold that’s reusable and compostable is very appealing.

Ease of use. It’s honestly pretty hard to mess this up -- just microwave according to the directions and pour. No measuring, no A/B mixture, no concerns about chemical contamination from latex or sulfur, etc.

Shelf life. Unlike silicones, which have a shelf life of anywhere from six months to three years depending on storage conditions, the SiliNOT! purports to be shelf-stable. It's compostable, so don’t bury it in your yard, but otherwise it appears that it could be kept on hand for years.

Cons

Bubbles. Honestly the most irritating thing about this stuff for me. I’m used to being able to see bubbles forming as I pour, tap them to the surface, and remove them. The fact that I poured four molds of the same object and never once got one without bubbles is super irritating.

Stickiness. I’m not a big fan of the tacky surface texture, and while I haven’t done any cold casting yet, I can imagine that it would be very difficult to clean out any pigment or mica powder that got where you didn’t want it. I probably wouldn’t use this for any kind of cold casting that required isolated colored areas or changing colors between casts.

Set time. The SiliNOT! may take longer to cool than a fast silicone would to cure when dealing with larger molds, so it’s not ideal for projects with a really tight turnaround. (But cosplayers would never be casting something the night before a con, right? We always plan ahead and never, ever procrastinate!)

Library life. The SiliNOT! may or may not structurally degrade over time the way urethane, latex, and tin cure silicones do, but I noticed even in my very limited casts that it was prone to having tiny bits of the mold (particularly at edges) stick and pull off. While I keep most of my platinum silicone molds for years and reuse them, I don’t feel that the SiliNOT! molds would hold up to repeated casting, and they’re far more sensitive to ambient temperature, so they’re probably best used for short term only. (I also wonder about the possibility of oil leaching out in long-term storage.)

Comparative Ranking

Ranking it against other mold-making materials, I’d place SiliNOT! below platinum-cure silicone in terms of performance, but maybe somewhere in the neighborhood of urethane and tin-cure silicone. It's definitely superior to latex. (Though to be honest, I'd rank Play-Doh above latex. I hate working with that stuff.)

Factoring in cost and environmental impact, it beats out urethane and tin-cure silicone. I'm still not sure if I'd rank it above platinum-cure silicone, though... Silicone costs much more and isn't eco-friendly, but the performance and lifespan is significantly better, so it still makes more sense for some projects.

Alginate is another type of material entirely, but in some ways SiliNOT! is comparable to it -- both are more cost-effective than silicone, both are biodegradable, both are skin safe, and both have long shelf lives. But SiliNOT! is easier to use for beginners than alginate, which has to be mixed to the right consistency and has an extremely short lifespan once poured.

Overall, I would recommend SiliNOT! for:

People who want accurate, non-shrinking molds but don’t have the budget for platinum-cure silicone

People who are committed to eliminating waste from single-use materials, and are willing to trade off a little performance for a more eco-friendly material

Projects with smooth surfaces and no indentations/sharp edges/undercuts where bubbles might stick (e.g. cabochons; simple geometric forms)

Projects where you need only one or two casts of something, rather than many casts from the same mold

Casting oddly-shaped pieces around which the mold needs to stretch in order to demold

Use with slow-curing resins that do not generate much heat

I would NOT recommend SiliNOT! for:

Extremely complex or detailed pieces, or pieces with a lot of surface texture that bubbles might stick to

Two-part molds

Projects requiring many identical casts out of the same mold

Molds that you intend to add to your library for future or repeat casting

Use with fast-curing resins, melted wax, melted Monster Clay, or any other material that emits heat

Cold casting with precise color application

My Overall Opinion

It's... okay? I will almost certainly keep SiliNOT! in my toolkit for certain specific applications. It's MUCH cheaper over the long term, I love the idea of recycling mold material, and there are some projects for which it will likely perform very well (those listed in the above bullet points). I will also admit that three days of working with it does not constitute a comprehensive familiarity with the product, and it might be the sort of thing that you get better at working with after more practice. (Just learning how to eliminate bubbles would go a long way toward making me adopt this for more projects!)

However, I don't quite buy the "better than silicone" tagline. It's definitely more difficult to get a perfect result, and there are some projects for which platinum-cure silicone is always going to be more reliable (e.g. high-temperature casting, mass production, large-scale life casting).

For those looking for a recommendation of whether or not to buy, I'd say look at your project budget and the applications for which you're going to be making molds, and let those factors guide which mold material you go with. People doing some kinds of projects are likely going to find this a godsend, while those doing different projects would probably hate working with it.
